Mbcs Error Building Mfc C++ Project with Visual Studio

MBCS Error building MFC C++ project with Visual Studio

This error message is due to the missing MBCS MFC package. Starting with Visual Studio 2013, MBCS portion of the MFC library has been broken out of the Visual Studio product into its own separate download. Installing this package and rebuilding should fix the problem.

Update for Visual Studio 2015

Starting with Visual Studio 2015, the entire MFC C++ library (including the MBCS pieces) is an optional install component. While installing VS2015, if you select C++ and MFC, you will also get the MBCS library.

Error preprocessor directives when building

The _MBCS symbol will be defined as a result of the settings in your project properties. Look at General->Character Set - this is what adds the required entries to the command line.

To continue using MBCS, you need to install the optional support from Microsoft here

As it notes in MSDN:

The code in your question actually gives a link to this blog post, which discusses the changes and includes a link to the download:

// Warn about MBCS support being deprecated: see http://go.microsoft.com/fwlink/p/?LinkId=279048 for more information.

So, you can either download the patch from the link above or migrate your application to UNICODE.

Visual Studio unable to recognise my MFC library for my webcam laser rangefinder code

right click your solution, go to properties and set the project properties to use Unicode instead.

Side-effect of deprecation of MBCS support for MFC in VS 2013

You can. Currently all my programs use the Unicode library. Except one older one, that includes very old code from previous versions and this program is needed for update support for this od version...

1. Currently there is an Addon that still supports MBCs.
2. Vote for it
3. As I understand the discussion (see comment of Mark Davis dated December 2014) such an Addon will be available up and including VS2015 (whatever Version is meant).

To be more precise what happens when you select "None" for the character set:

1. You program is linked against the MBCS Version of the MFC
2. Also the Windows SDK will Default to the MBCS Version of the API. So i.e. GetWindowTextA is calls instead of GetWindowTextW

So in fact. Setting _UNICODE and _MBCS to nothing just Defaults to _MBCS...

Internally the SDQ always checks a if UNICODE (not _UNICODE) is set. If not the MBCS Version is chosen.
